DESCRIPTION OF EMBODIMENTS

In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure more clearly, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present disclosure.

Matching background music based on video refers to the process of selecting and determining the background music that matches video data according to the content, style, rhythm, and other features of the video data after the video is captured or edited.

In the prior art, the above process is implemented manually, that is, the background music producer of the video data needs to interpret the content, style, rhythm and other attributes of the video data, and search for appropriate background music in a preset music library according to experience.

However, the time required to manually find the appropriate background music in a music library with large data volume is long while the requirements for the producer's accumulated experience and ability to interpret the video data are high, which decreases the data processing efficiency of finding the background music matching the video data and increases labor cost.

In view of the above-mentioned technical problems, the present disclosure provides a video data processing method, a video data processing apparatus, and a readable storage medium. It should be noted that the video data processing method, the video data processing apparatus, and the readable storage medium provided by the present application can be widely applied to application scenarios where it is necessary to search for music that matches video data, and these application scenarios include, but are not limited to, music production of movie video or entertainment video, automatic selection or automatic recommendation of video background music in entertainment video website or short video software, etc.

FIG. 1 is a schematic diagram of a network architecture on which the present disclosure is based. As shown in FIG. 1, in the present application, a user may input video data to the video data processing apparatus 2 by using the data input port 1, for the video data processing apparatus 2 to process and then output music data matching the video data to the user through the output port 3, where the video data processing apparatus may be a server or a server cluster that is installed locally or in the cloud, and may also cooperate with a data server 4 on which a music library is based to implement functions such as storing, processing, and reading music data.

In addition, the foregoing data input port 1, the video data processing apparatus 2, and the output port 3 have different forms according to different application scenarios.

For example, in the aforementioned scenario of music production for movie video or entertainment video, the data input port 1 and the output port 3 are present on a video editing interface of the movie video or entertainment video, that is, a user can upload video data to be processed to a local video editing software (i.e., the video data processing apparatus 2) through a data upload trigger component (i.e., data input port 1) provided by an interface of the video editing software, so that the local video editing software processes the video data and displays the processing result on a display component (i.e., data output port 3) provided by the interface of the video editing software.

For another example, in the aforementioned scenario of automatic selection or automatic recommendation of video background music in an entertainment video website or a short video software, the data input port 1 may be specifically combined with the video production port provided by the client of the entertainment video website or the short video software, that is, a user can upload video data to be processed to a server (i.e., the video data processing apparatus 2) on which the entertainment video website or the short video software is based by triggering a video production component (i.e., data input port 1) on the entertainment video website client or the short video software client, and after the video data is processed, the processing result is returned to the entertainment video website client or the short video software client, and displayed on a display component (i.e., the data output port 3) at the specified position of the client.

Each of the above structures should be combined with a specific scenario, and the existing form thereof will also have various possibilities which the present implementation will not limit.

FIG. 2 is a schematic flowchart of a video data processing method according to Embodiment I of the present disclosure.

As shown in FIG. 2, the video data processing method includes:

step 101, processing, according to a preset trained deep learning algorithm model, input video data to be processed to obtain a label vector of the video data, where the label vector includes a confidence score of the video data under each label;

step 102, determining, according to a label vector of each music data in a music library and a preset recommendation algorithm, a recommendation score of the label vector of each music data with respect to the label vector of the video data;

step 103, outputting, according to each recommendation score, music data matching the video data.

It should be noted that the execution body of the video data processing method provided by the present disclosure may specifically be the video data processing apparatus shown in FIG. 1.

Specifically, the present disclosure provides a video data processing method. First, a video data processing apparatus receives video data to be processed which is uploaded by a user through a data input port, and the video data may be recorded or produced in advance by the user and may also be recorded in real time by the user.

Subsequently, the video data processing apparatus will process the video data to be processed by using a preset trained deep learning algorithm model, and through the trained deep learning algorithm model, the video data processing apparatus will obtain a label vector corresponding to the video data. The label vector is used to represent the label component of the video data, that is, the label vector includes a confidence score of the video data under each label. Specifically, in order to achieve a fast match between video data and music data, a machine learning algorithm such as a trained deep learning algorithm model may be used to perform feature classification analysis on video data. The label can be preset, and should include multiple features in multiple dimensions, such as sadness, joy, and dullness under an emotional dimension; and such as rapidness, slowness, stableness under a rhythm dimension; and such as warmness, ice-coldness, abruptness and black-and-white under a hue dimension; and such as compactness and ease under a plot feature.

The label vector should include a confidence score for each feature of the video data in each dimension. The label vector may be, for example:

[(Emotion) sadness, joy, dullness, volatility, (rhythm) rapidness, slowness, stableness, fluctuation, (hue) warmness, ice-coldness, abruptness, black-and-white, (plot) compactness, ease, turbulence, mess]=[0, 0.25, 0.01, 0.02, 0.25, 0, 0, 0.02, 0.2, 0, 0.01, 0.01, 0.18, 0.01, 0.01, 0.03].

Of course, the present implementation does not limit the type of label in the label vector.

Optionally, the trained deep learning algorithm model in the present implementation includes at least: a convolutional neural network and a multi-layer perceptron; and correspondingly, the process of processing the video data by using the trained deep learning algorithm model may include: inputting the video data to be processed into the convolutional neural network to extract and obtain feature information of the video data, and inputting the feature information of the video data into the multi-layer perceptron to enable the multi-layer perceptron to perform vector-dimensional mapping on the feature information according to a preset label type to obtain the label vector of the video data. It should be noted that both the convolutional neural network and the multi-layer perceptron are relatively mature network architectures, and the present implementation does not limit the same. However, in order to analyze the video data to obtain a corresponding label vector, the present application sequentially performs the foregoing steps by using a convolutional neural network and a multi-layer perceptron, so as to implement the corresponding functions.

Subsequently, the video data processing apparatus determines, according to a label vector of each music data in a music library and a preset recommendation algorithm, a recommendation score of the label vector of each music data with respect to the label vector of the video data.

Specifically, the music library includes each music data which is pre-stored and the label vector of each music data. Further, when the music library is constructed, the following manner may be adopted: collecting music data, processing the collected music data by using the trained deep learning algorithm model to obtain the label vector of the music data; and storing the music data and corresponding label vector in the music library. It should be noted that the trained deep learning algorithm model provided by the present implementation can be used not only for processing video data but also for processing music data, and the processing manner thereof is similar to the foregoing implementation, thus details are not described herein.

Further, in the present implementation, the video data processing apparatus can sequentially obtain, according to the label vector of the video data and the label vector of each music data in the music library, a similarity between the label vector of the video data and the label vector of the each music data based on latent factor algorithm; and determine, according to each similarity, the recommendation score of each music data with respect to the video data. For example, the latent factor algorithm is a recommendation algorithm for calculating the matching degree based on scoring vector, and in the present implementation, the recommendation algorithm including the latent factor algorithm may be used to sequentially calculate the similarity between the label vector of the video data and the label vector of each music data in the music library in order to obtain the recommendation score of each music data, where the recommendation score can be understood as the ratio of an elemental composition of the video data to the same elemental composition of the music data, or the degree of similarity between the element compositions, that is, the higher the recommendation score, the more the music data matches the video data, i.e., it will be more adapted using the music data for the background music of the video data.

Finally, the video data processing apparatus will output, according to the each recommendation score, music data matching the video data. Specifically, the video data processing apparatus may output the music data in various manners, for example, by sorting the each music data in accordance with the each recommendation score and outputting a preset number of music data whose recommendation score is greater than a preset threshold as the music data matching the video data. Of course, it is also possible to output only the music data with the highest recommendation score. The output music data can be used for further screening by the user, and can also be used by backend component to perform further processing such as editing and integration on the music data and the video data.

In the video data processing method provided by the Embodiment I of the present disclosure, the technical means is adopted which includes: processing, according to a preset trained deep learning algorithm model, input video data to be processed, so as to obtain a label vector of the video data, where the label vector includes a confidence score of the video data under each label; determining, according to a label vector of each music data in a music library and a preset recommendation algorithm, a recommendation score of the label vector of each music data with respect to the label vector of the video data; and taking, according to the each recommendation score, the music data matching the video data as background music. By means of the above, and further a deep learning algorithm model and a recommendation algorithm, the music data matching the video data can be quickly determined, thus the data processing efficiency of finding the background music of the video data in the music library is effectively improved, and the labor cost is reduced.

Step 202, training the deep learning algorithm model to be trained according to labeled video data and/or labeled music data to obtain a trained deep learning algorithm model.

Specifically, the execution body of the video data processing method provided by the Embodiment II should be the video data processing apparatus shown in FIG. 1.

In the present implementation, first, a deep learning algorithm model to be trained may be built, where in order to facilitate processing of the video data, the deep learning algorithm model to be trained includes at least a convolutional neural network and a multi-layer perceptron structure. As described in the Embodiment I, the convolutional neural network can be configured to extract feature information of video data and/or music data; and the multi-layer perceptron structure can be configured to perform vector-dimensional mapping on the feature information according to a preset label type to obtain the label vector of the video data and/or the music data.

Subsequently, after completing the building of the deep learning algorithm model, the deep learning algorithm model to be trained may be trained according to labeled video data and/or labeled music data to obtain a trained deep learning algorithm model, where the labeled video data and/or the labeled music data are obtained by manual labeling, that is, according to the preset label dimension and feature dimension, manually scoring is performed to obtain corresponding labeling information, and by using the labeled data, the training of the built deep learning algorithm model can be realized, so that the trained deep learning algorithm model can learn the thinking of manually labeling and process the video data to be processed to obtain the corresponding label vector.

In addition, it should be noted that the trained deep learning algorithm model obtained in the present implementation is used for processing the video data to be processed in the Embodiment I, and the processing process is similar to that in the Embodiment I, and details are not described herein.
